Reliability Assessments: Concepts, Models, and Case Studies (International Series In Engineering And Computer Science #Vol. 206)
by Franklin Richard Nash, Ph.D.This book provides engineers and scientists with a single source introduction to the concepts, models, and case studies for making credible reliability assessments. It satisfies the need for thorough discussions of several fundamental subjects. Section I contains a comprehensive overview of assessing and assuring reliability that is followed by discussions of:• Concept of randomness and its relationship to chaos• Uses and limitations of the binomial and Poisson distributions• Relationship of the chi-square method and Poisson curves• Derivations and applications of the exponential, Weibull, and lognormal models• Examination of the human mortality bathtub curve as a template for components Section II introduces the case study modeling of failure data and is followed by analyses of:• 5 sets of ideal Weibull, lognormal, and normal failure data• 83 sets of actual (real) failure data The intent of the modeling was to find the best descriptions of the failures using statistical life models, principally the Weibull, lognormal, and normal models, for characterizing the failure probability distributions of the times-, cycles-, and miles-to-failure during laboratory or field testing. The statistical model providing the preferred characterization was determined empirically by choosing the two-parameter model that gave the best straight-line fit in the failure probability plots using a combination of visual inspection and three statistical goodness-of-fit (GoF) tests. This book offers practical insight in dealing with single item reliability and illustrates the use of reliability methods to solve industry problems.
Reliability-Based Optimization of Floating Wind Turbine Support Structures (Springer Theses)
by Mareike LeimeisterThis book pursues the ambitious goal of combining floating wind turbine design optimization and reliability assessment, which has in fact not been done before. The topic is organized into a series of very ambitious objectives, which start with an initial state-of-the-art review, followed by the development of high-fidelity frameworks for a disruptive way to design next generation floating offshore wind turbine (FOWT) support structures. The development of a verified aero-hydro-servo-elastic coupled numerical model of dynamics for FOWTs and a holistic framework for automated simulation and optimization of FOWT systems, which is later used for the coupling of design optimization with reliability assessment of FOWT systems in a computationally and time-efficient manner, has been an aim of many groups internationally towards implementing a performance-based/goal-setting approach in the design of complex engineering systems. The outcomes of this work quantify the benefits of an optimal design with a lower mass while fulfilling design constraints. Illustrating that comprehensive design methods can be combined with reliability analysis and optimization algorithms towards an integrated reliability-based design optimization (RBDO) can benefit not only the offshore wind energy industry but also other applications such as, among others, civil infrastructure, aerospace, and automotive engineering.

Reliability Engineering: Probabilistic Models and Maintenance Methods, Second Edition
by Joel A. NachlasWithout proper reliability and maintenance planning, even the most efficient and seemingly cost-effective designs can incur enormous expenses due to repeated or catastrophic failure and subsequent search for the cause. Today’s engineering students face increasing pressure from employers, customers, and regulators to produce cost-efficient designs that are less prone to failure and that are safe and easy to use. The second edition of Reliability Engineering aims to provide an understanding of reliability principles and maintenance planning to help accomplish these goals. This edition expands the treatment of several topics while maintaining an integrated introductory resource for the study of reliability evaluation and maintenance planning. The focus across all of the topics treated is the use of analytical methods to support the design of dependable and efficient equipment and the planning for the servicing of that equipment. The argument is made that probability models provide an effective vehicle for portraying and evaluating the variability that is inherent in the performance and longevity of equipment. With a blend of mathematical rigor and readability, this book is the ideal introductory textbook for graduate students and a useful resource for practising engineers.

Reliability Modelling: A Statistical Approach
by Linda C. WolstenholmeReliability is an essential concept in mathematics, computing, research, and all disciplines of engineering, and reliability as a characteristic is, in fact, a probability. Therefore, in this book, the author uses the statistical approach to reliability modelling along with the MINITAB software package to provide a comprehensive treatment of modelling, from the basics through advanced modelling techniques.The book begins by presenting a thorough grounding in the elements of modelling the lifetime of a single, non-repairable unit. Assuming no prior knowledge of the subject, the author includes a guide to all the fundamentals of probability theory, defines the various measures associated with reliability, then describes and discusses the more common lifetime models: the exponential, Weibull, normal, lognormal and gamma distributions. She concludes the groundwork by looking at ways of choosing and fitting the most appropriate model to a given data set, paying particular attention to two critical points: the effect of censored data and estimating lifetimes in the tail of the distribution.The focus then shifts to topics somewhat more difficult:the difference in the analysis of lifetimes for repairable versus non-repairable systems and whether repair truly ""renews"" the systemmethods for dealing with system with reliability characteristic specified for more than one component or subsystemthe effect of different types of maintenance strategiesthe analysis of life test dataThe final chapter provides snapshot introductions to a range of advanced models and presents two case studies that illustrate various ideas from throughout the book.
Reliability Modelling and Optimization of Warm Standby Systems
by Rui Peng Qingqing Zhai Jun YangThis book introduces the reliability modelling and optimization of warm standby systems. Warm standby is an attractive redundancy technique, as it consumes less energy than hot standby and switches into the active state faster than cold standby. Since a warm standby component experiences different failure rates in the standby state and active state, the reliability evaluation is challenging and the existing works are only restricted to very special cases. By adapting the decision diagrams, this book proposes the methodology to evaluate the reliability of different types of warm standby systems and studies the reliability optimization. Compared with existing works, the proposed methods allow the system to have an arbitrary number of components and allow the failure time distribution of components to observe arbitrary distributions. From this book, the readers can not only learn how to evaluate and optimize the reliability of warm standby systems but also use the methods to study the reliability of other complex systems.

Reliability Theory Based on Uncertain Lifetimes
by Ying LiuThis book, to reflect the system’s diverse, relevant characteristics, uses three different mathematical tools, namely probability theory, fuzzy theory and random fuzzy theory, to model and analyze the reliability of each system. Reliability system engineering is an interdisciplinary area that chiefly focuses on the lifecycle characteristics of products and involves many fields of basic mathematics, technical science and management science. In recent years, there have been many books on reliability theory, but comparatively few on the reliability of mathematical models, or the reliability of mathematical models based on single probability theory or fuzzy theory. The findings presented here will not only enrich and expand traditional reliability theory, but also promote the development of related disciplines, lending the book considerable theoretical significance.
Religion in America (Sociology in the Twenty-First Century #6)
by Lisa D. Pearce Claire Chipman GillilandWritten in an engaging and accessible tone, Religion in America probes the dynamics of recent American religious beliefs and behaviors. Charting trends over time using demographic data, this book examines how patterns of religious affiliation, service attendance, and prayer vary by race and ethnicity, social class, and gender. The authors identify demographic processes such as birth, death, and migration, as well as changes in education, employment, and families, as central to why some individuals and congregations experience change in religious practices and beliefs while others hold steady. Religion in America challenges students to examine the demographic data alongside everyday accounts of how religion is experienced differently across social groups to better understand the role that religion plays in the lives of Americans today and how that is changing.
Religious Diversity in Southeast Asia and the Pacific
by Gary D. Bouma Rodney Ling Douglas PrattReligious diversity is now a social fact in most countries of the world. While reports of the impact of religious diversity on Europe and North America are reasonably well-known, the ways in which Southeast Asia and Asia Pacific are religiously diverse and the ways this diversity has been managed are not. This book addresses this lack of information about one of the largest and most diverse regions of the world. It describes the religious diversity of 27 nations, as large and complex as Indonesia and as small as Tuvalu, outlining the current issues and the basic policy approaches to religious diversity. Southeast Asia and the Pacific Islands are portrayed as a living laboratory of various religious blends, with a wide variance of histories and many different approaches to managing religious diversity. While interesting in their own right, a study of these nations provides a wealth of case studies of diversity management - most of them stories of success and inclusion.
The Religious Roots of Longevity Risk Sharing: The Genesis of Annuity Funds in the Scottish Enlightenment and the Path to Modern Pension Management
by Moshe A. MilevskyThis book presents a unique historical study on the origins of longevity risk management and its links to religious institutions in the eighteenth century. Throughout history, monarchs, affluent patrons, and wealthy benefactors routinely pledged to provide their devotees with pensions or life annuities, mirroring the biblical concept of ‘daily bread for life’. Until the eighteenth century, however, the uncertainty around the longevity of beneficiaries’ lives and the difficulty of budgeting for random financial obligations had posed economic challenges that often led to insufficient funding and high default rates. This book narrates the genesis of longevity risk pooling and the first successfully funded annuity scheme in history, an eventual prototype for national pension plans around the world. It examines how a group of Protestant clergymen, scientists, and intellectuals associated with the Presbyterian Church of Scotland pioneered innovative methods for setting up a reversionary annuity and widow’s pension plan, guided by actuarial principles. Unknown to many, the economist Adam Smith, and other literati of the Scottish Enlightenment, invested in this novel annuity. Illuminating the social and theological contexts of this scheme, the book argues that religious belief played a critical role in the development of best practices around the prudent management of longevity risk. The practices, values and beliefs in divine probabilities were at the heart of these thought leaders’ confidence in long-term financial projections. Shedding light on this fascinating aspect of actuarial history by an examination of the archival records, while also linking to contextual discussions of modern pension challenges, this book will be of interest to scholars and readers interested in finance, insurance, pensions, and religion.
Remote Sensing of Hydrometeorological Hazards
by George P. Petropoulos Tanvir IslamExtreme weather and climate change aggravate the frequency and magnitude of disasters. Facing atypical and more severe events, existing early warning and response systems become inadequate both in scale and scope. Earth Observation (EO) provides today information at global, regional and even basin scales related to agrometeorological hazards. This book focuses on drought, flood, frost, landslides, and storms/cyclones and covers different applications of EO data used from prediction to mapping damages as well as recovery for each category. It explains the added value of EO technology in comparison with conventional techniques applied today through many case studies.
